Which organ controls the production of insulin and glucagon?

• A. Liver
• B. Pancreas
• C. Kidneys
• D. Gallbladder

Answer: (B)

The pancreas is the organ responsible for controlling the production of insulin and glucagon, two critical hormones that regulate blood sugar levels. It plays a vital role in the endocrine system, functioning to maintain glucose homeostasis in the body. The pancreas contains clusters of cells known as the islets of Langerhans, which include beta cells that produce insulin and alpha cells that produce glucagon. Insulin is released when blood sugar levels are high, facilitating the uptake of glucose by cells for energy or storage. Conversely, glucagon is released when blood sugar levels are low, prompting the liver to release stored glucose back into the bloodstream. This dual action helps to keep blood sugar levels stable, demonstrating the important regulatory function of the pancreas in metabolic processes. In contrast, the liver primarily acts as a storage site and plays a significant role in metabolic processes, but it does not directly produce insulin or glucagon. The kidneys are involved in filtering blood and regulating electrolytes and waste products but are not responsible for hormone production in this context. The gallbladder primarily stores and concentrates bile for digestion and does not play a direct role in the production of hormones like insulin and glucagon.
